Is it possible to use a primitive type (int) in as a generic type in Java?

Specifically, with a SortedMap<Vector<String>, int> I get "dimensions expected after this (int) token." Help!

Konrad is correct. Alternately, you can use the trove class TObjectIntHashMap to map Objects to primitive ints.

No, this is not possible. Use Integer instead. Autoboxing takes care of the rest (i.e. for most purposes you can program as if you had actually used int because Java converts to and from Integer automatically for you).
